Daniel Latypov 1f0e943df6 Documentation: kunit: provide guidance for testing many inputs
usage.rst goes into a detailed section about faking out classes, but
currently lacks wording about how one might idiomatically test a range
of inputs.

Add a new chapter for "Common Patterns" and group "Isolating behvaior"
and this new section under there.

Give an example of how one might test a hash function via macros/helper
funcs and a table-driven test and very briefly discuss pros and cons.

Also highlight the KUNIT_EXPECT_*_MSG() variants (that aren't mentioned
elsewhere [1]) which are particularly useful in these situations.

It is also criminally underused at the moment, only appearing in 2
tests (both written by people involved in KUnit).
